While I'm pen testing, I came across these values mapping to a store ID. These values are gathered across three different accounts.
0015400000jpjcEAAQ
0015400000jrjH7AAI
0015400000jtDS9AAM
It's not a hash or base64. It doesn't look encrypted either as there are 10-bytes static values. The last 8-bytes tho, what can I deduce from this?
